HOT-AIR- RADIATOR.

sp ecif'ication of l'ietters Patent.

To all whom it may concern:

Be it known that we, DAVID REYAM, a resident of Wilmington, in the county of New Castle and State of Delaware, and Moses MAYER, a resident of Freeport, in the county of Nassau and State of New York, both citizens of the United States, have invented a new and Improved Hot-Air Radiator, of which the following is a full, clear, and exact description.

This invention relates to improvements in heating devices and more particularly to a hot air radiator designed to be used in connection with hot air heating systems having a wall pipe for conveying heat from the heating drum of a stove or furnace to the various rooms of the house or building.

An object of the invention is to provide an improved radiator which in general appear ance simulates an ordinary steam or hot water radiator but which comprises anovel construction including a plurality of units capable of ready assemblage and equipped with novel means to adapt it for-attachment or to be coupled with the register opening in a wall so that the radiator will be made practically continuous with the wall pipe in such a manner as to draw the hot air therefrom, whereas ordinarily the tendency of the hot air to escape through the usual register is at a minimum, thus producing greater heating efficiency.

A further object of the invention is to provide a radiator of the class described which is of the novel construction, the units each being formed of sections of sheet metal and the units necessary to composea radiator being connected so that all of the units are placed in free communication witheach other while permitting the hot air to be deflected into the upper part of each individually, while novel means are provided for regulating the discharge of the hot airfrom each unit so as to control the heatingefficiency of the radiator or the heat radiated therefrom, and also to provide means to avoid any counter'currents of air or pre venting the air escaping from the opposite sides of the radiator units near their upper ends from choking or blocking the free escape of the hot air.

With the aboveand other objects in view, the invention resides in the peculiar combinationand arrangement of parts tobehe'reinaftermore fully described, illustrate and providin a soecial hot air claimed, it being also an object to provide a devlce which is simple in construction, durable and eflicient in operation.

Reference is to be had to the accompanymg drawings forming a part of this specifica-tlon, in which similar characters of reference indicate corresponding parts in all the views, and in which Figure 1 is a front elevation of our improved hot air radiator; Fig. 2 is a rear elevation thereof; Fig. 3 is a vertical sectional view taken on the line 33 of Fig. 1; Fig. 4 is an enlarged cross sectional view taken on the line i4r. of Fig. 3; and Fig. 5 is an enlarged horizontal sectional View taken on the line 55 of Fig. 2.

tension of the wall pipe, such being designed to usually receive an ordinary hot air register for controlling or regulating the discharge of the heated air into each room.

Owing to the fact that these registers lie flush with the face it of the wall of the room, the tendency of the air circulating in the room to create a suction in the wall pipe to draw the heated air therefrom is reduced to a minimum, and this is further the result of the fact that the heated air from the wall pipe must take a lateral path in order to be discharged into the room.

In this manner the heating efiiciency of a hot air heating system, employing a stove or furnace, is reduced to a minimum and it is therefore the object of the present invention to overcome these disadvantages by radiator for use with such heating systems, whereby the proper amountof heat will be drawn from the wall pipe into roomsbelow the top room supplied with heat through the medium of such a heating system and thereby provide for greater heating efficiency while requiring no special wall structure or modification of the walls as adapted to receive the usual registers. For this purpose a radiator 15 is provided, the same being made up of a plurality ofunits 16 and eaoh'unit preferably are therefore restricted at the points of juncture of the portions with the curved portions 19 of the sections. The curved portions 19 are convexly arcuate outward so as to provide concaved inner faces, and while one section of each end unit is left rectilinear, one side thereof and the opposed sides of each intermediate unit are formed with apertured outpressed extensions 21 near the upper and lower ends thereof. The sections are held together by means of bolts 22 passing through the horizontally alined upper and lower series of apertures in the sections of the units at the rectilinear sides of the end units and through the extensions at the inner sides of said units and the opposed sides of the intermediate units, thus providing means to assemble any desired number of units in a radiator, depending upon the .size of the'room or rooms and the amount of heat required under the particular existingcircumstances or the locality and thus the weather conditions. 7

As heretofore specified, the sections of the units are made up of sheet metal and if desired the end units may be extended to produce legs 23 for supporting the radiator adjacent to the wall. However, if the legs 23 are omitted the radiator may be supported upon a bracket or brackets 24- attached to the baseboard 25 beneath the register opening while the wall and certain units of the radiator have straps or loops 26 attached thereto for'engagement by a U-coupling 27 for connecting said parts and holding the radiator at a spaced distance from the wall or in an upright position. In order to place the radiator in communication with the wall pipe, to establish communication of all of the units with each other and adapt the device for register openings of varying sizes,

' the inner or rear portions of the units are severed or cut out, asshown at 28, and the edges of the recesses thus provided connected by web portions or partitions 29 which close the spaces between theunits at the lower portions of the latter to provide an interior space 30 establishing communication with the interior of all of the units. These web portions or partitions produce top walls 31 terminating about midway of the height of the radiator and bottom walls 32 terminating above the loop extensions '21, while the web portions proper, which extend vertically, terminate about midway of the depth of the radiator units so as to be contiguous with a line connecting the bolts 22, or substantially so. In this manner the units of the radiator will be uniformly heated and aside therefrom will have the remaining areas substantially independently arranged to receive the heated air for independent circulation. The inner side of the casing thus produced is open and at the top and side edges thereof is provided with a slide groove or guideway 33 designed to take a carrying plate 34: vertically from the bottom and in such a manner that the plate will close the back of the casing with the excep' tion of a space produced by a frame 35 projecting therefrom, such frame being designed to enter the register opening, as shown in Fig. 3 of the drawings, so as to place the register in communication with the wall pipe, whereby the hot air passing up the wall pipe will be discharged into the radiators on one or more floors of a house o building.

The function and purpose of reinovably attaching the plate 34 to the radiator proper is to allow for the construction thereof with projecting frames of varying sizes so that no modification of the heating structure is necessary in order to place the same in cou1- munication with the wall pipe where the register openings vary in size. It is to be understood, however, that such plate is made of suiiicient size to adapt the radiator to an opening of maximum size so that the device is one of more general application than would otherwise be the case. In this manner communication is established between the radiator as a whole and the wall pipe, as well as with the several units of the radiator, and in order to control the heating cfliciency as the hot air escapes into the units of the radiator, the sections of the units or sides thereof which oppose each other, that is, the opposite sides of the interu'iediate units and the inner sides of the end units, are provided with a plurality of openings 36 arranged in a multiple of rows concentric to the upper connecting bolt as a center, and secured to the sections on the inside are deflector plates 87, one of such plates being provided for each end unit to extend from the outer side thereof and curving upward and across these units to a point slightly above the openings at the opposite sides, while two of such plates are provided at the intermediate ends and diverge upwardly and laterally from the central. portions thereof in such a manner as to provide deflectors to discharge the heated air through the openings above mentioned. These deflector plates are of concavo-convex formation and are riveted, bolted or otherwise attached to the sections of the units as shown at 38.

Mounted on the bolts .22 are sleeves 39 and also mounted on the upper bolt are valve bolt as a pivot. These plates fit in theex tensions 21 and are otherwise of substantially semicircular form in plan so as to be capable of rotation within the units to permit the openings 36 to be placed into and out of registration with corresponding openings 4:1 in the plates. For this purpose each inner section 19 is provided with an arcuate slot 42 through which an extension or lever 43 of an adjacent valve plate projects in convenient position to be oscillated. for correspondingly moving a valve plate to partly or totally uncover the openings 36 or to on tirely close the same as desired, depending upon the amount of heatrequired. In order to permit the valve plates to be held in adjusted positions the sleeves 39 at their ends engage said plates and are brought into frictional engagement therewith upon the nuts on the extremities of the upper bolt 22 being tightened, and the sleeves additionally serve the dual function of holding said valve plates in adjusted positions against the inner faces of the sections 19 as well as to brace the units and the radiator as a whole.

With the radiator spaced from the wall as shown and described, the air in the room tends to circulate under and upward in back of the same between the radiator and the wall so that a suction or draft is created in the radiator units to draw the heated air from the wall pipe into the radiator through the connection establishing communication between the two. In this manner a greater heating efliciency is produced than with the ordinary register which lies flush with the wall or substantially so, inasmuch as the radiator as a whole forms a section of pipe or box practically making continuous the wall pipe in the room. In this manner it is necessary to providethe regulating or valve plates to control the draft and the discharge of hot air which, owing to the use of the deflector plates or distributors and the arrangement of the openings as specified, will be caused to take effect in such a manner that as it is drawn fromeach unit or section it will be directed upward. in this manner counter-currents of air or interferin eddies will be avoided by preventing the air from going directly across the spaces b tween the units which would result in the blocking and choking of the flow of air with obvious disadvantages in the point of heating qualities. To further control the heat radiated, means are provided in the form of ahand operated vertical shaft l4: journaled in the top and bottom portions of the rear extension of the radiator and connected to one of a plurality .of pivotedshutters 4-5 suitably connectedas shown at elite cause their slmultaneous rotation to open or closed positions upon the. partial rotation or oscillation of the shaft through the medium of the handle or lever 47 thereof. This handle; is preferably disposed near the top of the radiator and being inthe space betweenthe radiator and .therwall will be out of the way but in convenient position'to be operated. It will also be observed that the slots as will, through the medium of their end walls, serve to limit the turning movement of oscillation of the valve or controlling plates 40 so that the openings 41 will aline with the openings 36 at one limit of the movement of each plate, but will be moved out of alinement with respect thereto to close the openings 36 through the medium of the solid intermediate portions of the plate when oppositely shifted.
